Machining Centers & Cells
for the Korean automotive industry. Machining centers are designed for heavy-duty machining and pocket milling with Hwacheon’s Optima cutting feed optimization, and HTLD tool load detection software.
Hwacheon’s Vesta 1050B vertical machining center features four wide hand-scraped box guideways in the Y axis and wide box ways in the X and Z axes for machine rigidity. A two-speed gear-driven spindle with integrated drive provides high-speed cutting and delivers high torque. All Hwacheon spindles are oil- cooled, including the gearbox to mini- mize thermal displacement and promote long spindle life. The geared headstock machining center is capable of heavy roughing cuts as well as fine finish ma- chining. The Vesta universal machine is available with 40 or 50-taper, 6000 or 8000-rpm spindles that produce micron accuracy in heavy-duty cutting. Hwacheon’s tool load detection (HTLD) software provides real time mea- surement of tool load constantly moni- toring tool damage and deterioration for prevention of complete tool failure caus- ing workpiece damage for consistent and safe machining. The HTLD system measures tool load frequently, as often as every eight msecs.
The FVM-104160DC is perfect for lean, repeatable mass production of large and heavy workpieces. The slanted Y- and Z- axes increase the slideway surface and eventually distribute the load in the area.
The series also features these benefits:
• The FVM double-column VMC has an extremely rigid and stable structure base on oversized columns, extra-wide spacing of box ways on a slanted Y-axis and a close symmetrical design of the Z-axis.
• The four heavy-duty linear roller ways of the X-axis support the table and boost moving speed, dramatically reducing stick-slip problems caused from box ways machines and increasing the machines positioning accuracy.
• The XY-axis runs with a Class 3 high-precision, double-nut, pre-tensioned ball screw. The coolant circulation in the 3" large balls crews eliminates thermal building and ball screw deformation, helping to maintain high-positioning accuracy and repeatability.
• The 50-taper, cartridge-type, air-purge, 6000rpm with 30 HP spindle is driven by a two-speed gearbox with low speed for extra-high torque output during heavy cutting. It generates a maximum torque of 449 ft.-lbs.

Optima cutting feed optimization software uses an adaptive control meth- od to regulate the feed rate in real time to sustain a consistent cutting load while machining. As a result, cutting tools are less prone to damage and machining time is reduced. The system controls the feed velocity to maintain consistent cutting load. Features include a graphic display of tool load and feed rate, conve- nient operation using G-code program- ming, and a number of data sets for specific tool and process control. For die-mold applications Hwa-
cheon’s Sirius three-axis vertical machining centers feature 20,000-rpm high-speed spindles for the UM and UL+ models and 12,000-rpm spindle for the UX model. The machines are equipped with integral motor spindles with jacket cooling and oil-jet cooled
